Oh i understand that totally. I've been working on cakes since I was about 5 when my mom let me loose with a start tip and a white cake but just recently was able to get my hands on some fondant and gumpaste. About 2 years in and i'm still a bit rough.
If your environment is very dry, you can try using a humidifier to add some moisture in the air. You also probably need to knead your fondant more before using. The more you knead it the softer it gets and you'll have more time to work it.
Lastly, I always try to get everything ready and prepared before I start rolling out my fondant. Once my fondant is rolled out I know exactly what I'm gonna do and get straight to it. Mise en plus = win!
